Class DefaultBinaryManager

java.lang.Object

org.nuxeo.ecm.core.blob.binary.AbstractBinaryManager

org.nuxeo.ecm.core.blob.binary.LocalBinaryManager

org.nuxeo.ecm.core.blob.binary.DefaultBinaryManager

All Implemented Interfaces:

BinaryManager

public class DefaultBinaryManager
extends LocalBinaryManager

A simple filesystem-based binary manager. It stores the binaries according to their digest (hash), which means that no transactional behavior needs to be implemented.

A garbage collection is needed to purge unused binaries.

The format of the binaries directory is:

• data/ hierarchy with the actual binaries in subdirectories,
• tmp/ temporary storage during creation,
• config.xml a file containing the configuration used.

Method Detail

getBinary

public Binary getBinary(Blob blob)
                 throws IOException

Description copied from interface: BinaryManager

Saves the given blob into a Binary.

Returns a Binary representing the stream. The Binary includes a digest that is a sufficient representation to persist it.

If the blob is a temporary FileBlob, then the temporary file may be reused as the final storage location after being moved.

Specified by:

getBinary in interface BinaryManager

Overrides:

getBinary in class AbstractBinaryManager

Parameters:

blob - the blob

Returns:

the corresponding binary

Throws:

IOException

storeAndDigest

protected String storeAndDigest(FileBlob blob)
                         throws IOException

Stores and digests a temporary FileBlob.

Throws:

IOException
